HOWARD S. HART AND LYLE B. MARCY, OF NEIV BRITAIN, CONNECTICUT, ASSIGNORS TO THE I-IART & COOLEY COMPANY, OF NEW BRITAIN, CONNECTICUT, A CORPORA- TION OF CONNECTICUT.

Application filed July 31, 1917.

a To all whom it may concern:

Be it known that we, HOWARD S. HART and LYLE B. MARoY, citizens of the United States of America, residing at New Britain, Conn, have invented a new and useful Top Plate for Registers and Ventilators, of which the following is a specification.

Our invention relates to an improved register and ventilator. The object is to provide an improved construction, particularly as to the perforated top plate. By availing of my invention such a plate can be successfully made of very light material with the openings of maximum size, the parts being so constructed and arranged as to withstand heavy weights.

In the drawings Figure 1, is a plan view of one corner of a register top plate and associated parts.

' Fig. 2, is a view of the under side of a portion of such a plate and associated parts.

Fig. 3, is an end elevation of part of a register.

Fig. 4, is a cross section of the top plate and associated parts.

Fig. 5, is a sectional view partly in elevation of certain parts. 7

Fig. 6, isa cross section on the line -6-6 of Fig. 1.

Fig. 7, is a perspective view of a detail of the construction.

1 represents the border of a ventilator plate suitable for use as a register top plate. In such plates it is highly desirable to have openings of as large area as possible so as to permit of the free passage of hot or cold air. To that end we form the plate of sheet metal and punch out suitable air passages 2, 2, 2. The cross bars at the sides of each of the openings are arched in cross-section and the sides or flanges thus formed are folded together, or very close together for the purpose of making all openings of the greatest possible area. At each of the junction points of several cross bars we form pockets 3, 3 on the under side of the plate, said pockets being formed between the depending flanges which continue in a curve around the corners of the openings. 4, 4 are reinforcing beams provided with one or more upwardly projecting lugs 5, 5 so spaced that when a bar 4 is placed on edge underneath the top plate, said lugs 5, 5 will project into said pockets 3, 3 so as to hold the beam 4 in aline- Specification of Letters Patent.

ment with one of the cross bars of the plate, whereby the beam may not be visible when the plate is viewed from above. The lugs 5, 5 thus pocketed, prevent the lateral deflection or bending of the beam 4 when a load is applied to the top plate. The ends of each beam are of course provided with suitable means for fastening the same in such a position that it will support the perforated part of the top plate when a load is applied thereto. One obvious expedient for supporting the cross beam 4 may comprise a pair of brackets 6, 6 welded or otherwise secured to the under side of the border of the top plate 1. These brackets may have openings into which the ends of the beam 4 may project, which ends are preferably somewhat reduced as at 7, 7 to project into said openings. When the top plate is used in connection with a register it should be provided with one relatively elongated opening 8 to afford clearance for the knob 9 of an operating means for controlling the osition of the slats 10, 10. The particular orm of this operating means is immaterial but, since it usually includes a slide 11, we preferably cut away one end of each beam 4 as at 12 to afford clearance for said slide 11 orfor any parts that may be associated therewith that need clearance space for free movement.

The lugs 5, 5 not only prevent the beam 4 from bending laterally, but they likewise hold the beam from endwise displacement thus making it unnecessary to lock the beam at the ends against endwise displacement. Each beam 4 may be made of substantially the thickness of the two drawn-together flanges of the cross bar under which the beam is located thus gaining a-maximum of supporting power without offensive appearance since the beam is hidden by the overlying cross bar of the plate when viewed from above. In the preferred construction of course the lugs 5, 5 should be of such a size as to neatly fit within the respective pockets designed to receive the same at the under side of the junction points of the cross bars.

In the preferred construction the beam 4 is thicker than any space that may be left between the drawn together flanges and yet the displacement of the beam is reliably pre vented by the lugs which engage the plate at intervals by projecting into the pockets at fiangesson the under side-of said plate at the:

junction points of: said cross bars, a reinforclngbeam supported, at its ends underneath said plate, sa1d beam being arranged edgew ise with respect to said plate and; in.
